Given numbers are 995,221,975,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,221,975,555 is 122041725.
Find LCM of 995,221,975,555 with Prime Factorization
| 3 | 995, 221, 975, 555 |
| 5 | 995, 221, 325, 185 |
| 13 | 199, 221, 65, 37 |
| 199, 17, 5, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 199 x 17 x 5 x 37 = 122041725
Therefore, the lowest common multiple of 995,221,975,555 is 122041725.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
995 x 221 x 975 x 555 = 118990681875
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
995 : 1, 5, 199, 995
221 : 1, 13, 17, 221
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,221,975,555, is 1.
Now, the common factors can be found like this.
995:5x 199
221:13x 17
975:3x 5x 5x 13
555:3x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 13 = 975
Therefore, the value for common factors is 975.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 118990681875/(1x975)
LCM = 118990681875/975
LCM = 122041725
Thus, we can understand that the LCM of 995,221,975,555 is 122041725.
